One of my readers asked me what platform I use for my docker containers in the lab. He assumed it is one of the public cloud platform providing such service. This is not true. I run few containers in public cloud, but this is not cost-optimal for lab tests. Especially in the way I sometimes work, when there might be few hours gap between the tests. I run all the containers locally on my own infrastructure which does not consist of few racks in mine basement. Actually, it is very small, so it has to be resource-optimal. I decided that for now, VMware Photon OS Project is the best solution for me.
